IMPROVEMENT IN HEDDLE-MACHINES.

Wmv- The S'hedulereferred to in these Lettera Patent andl making part of the same,`

`L'Pn'rnn PHILIP, of Stockportfm the county of Columbia and State of New York, have invented certain Improvements in Wire-Heddle Machines, of which the following is a specification. l

The first'part ot' my invention consists in a novel method of forming the central or warp-eye of a wirelieddle,'by twisting the wires at one end of' the eye, either wholly or in part, in advance of forming the twist attheopposite end, and by. relieving the gripe of the twisting device ,lrst closed in time to give slack suicient for thetwisting at the opposite end', for thepurpose ofefi'ecting the formation of the eye without straining or marring the wires. The second part of my invention`.consists of thepinchers, provided with a`tooth, around which the central or warp-eye is formed, and adapted to receive a slight lateral motion, sufficient to accommodate or allow the taking up of slackl of the wire required for the twist at each end ofthis eyc.- l -My inventionfurther consists in a novel combination of mechanism to successfully carry out .the meth-` ods above set forth, .whichwill be more specifically pointed out in the subjoined description and claim;

Description of the Accompanying Drawing. Figure 1 is a side elevation oi' a portion ot' a 4inachine, showing ho`w my improvements are applied.l Figure 2 is a birds-eye or-plan view of the same. Like let-ters on each tigure indicate like parts.

General Description.

My improved devices have been applied upon the machine known as the Ifinkle wire-'heddle machine, but the same may be applied to, and employed on other machines'used for this purpose.

They consist, principally, oi' two hollow `shafts' or cylinders, AA'1 journaled in the same line, but inwireis .not only drawn into, but. quite through the two cylinders, A A', and double, so that there are two wires employed, and operated with, in the process of making hcddles.

Heretofore the griping and twisting of the wire have been done simultaneously by both cylinders, or at both. ends of the warp-eye at the same time. This basso strained the wire, owing to the want oi' slack sufficient to form the twist, that a proper shape could not be `given to the eye, and the twist could not be made sufficiently. tight without danger of breaking thel wire.

My improvements obviate these objections, by twisting either end of the eye in part, or in full, while the opposite end of the heddle is released :and tiee, so that the wire.`can yield tothe contractionor short'- en ing required by the twist.

To dothis I place upon the cross-shaft D two cams, a a', of such form asto operate the two horizontal slide-bars b b";these are connected with the collars C C at their-opposite ends by means of the forks g g',

resting in grooves in the collars, and move or slide them laterally in succession, that is, one after the other,on their respective shafts. O i' course, the jaws moved by these collars are operated in a corresponding succession.

This operation would be more clearly understood it' each collar and pair oi' jaws were allowed to'com- "plete their work, and to release the wire before the others begin to operate, which is easily done by adjusting the cams a a. But, for the sake oi' expedition, the perfectness of the heddle being preserved,

I 'arrange or adjust theseoams so that one of the collars, and its accompanying device for grasping the 'wire,'are allowed to only partially complete their work before the others are made to commence their work.

successively cease to act. 4

vIn all wire-heddlemachines Vheretofore ,in use the pinchers B, carrying the eye-forming tooth, that aroundwhich the central or warp-eye. is lformed, are'ixed and stationary, having no lateral motion. By' my device, these pinchers are made to move laterally, so as to conform to and accommodate the twist ot' the wire at each end of the eye, by means of the slide-rod e, which is actuated by another small cam, d, on the cross or counter-shaft I).

The spring operating against the opposite side of the pinchers, restores them to their place, ready to be moved again on the return of the cam d.

The operation ofthe heddle-machiue has been suficient-ly hereinhefore described, both with and without my improvements, not to require recapitulatiom What I claim as my invention is- 1. The method herein described of forming the warp-eye of a wire-heddle, by making the twist at one end of the eye, either wholly or in part, before the twisting at the other end. is commenced, and relieving the gripe of the twistingfdevice rst closed in time'to give slack suiiicient ior'the twisting at the op- The springs c c serve to rest-ore the slide-bars b b'A .back to their places acr their respective cams aa' ate mechanism, a lateral motion, as set forth, to correspond with and accommodate the slack required for the twist at each end of the eye of the lleddle.
